Hi there...

 

Question...: "What is 25 to the fourth power?"

 

Here's an example...
The problem "2 to the 4th power", which basically means "(2^4)".

 

Knowing this we can do the following.

"(2^4)=((2^2)^2)=(4^2)=(4*4)=16"

 

From that we know how to solve your problem.
"(25^4)=((25^2)^2)=(625^2)=(625*625)=?"

 

I hope that helped a bit?


Kind regards
BizzyX

Why do you need all of those brackets ?

They're distracting.

Not much.  Here's how to do it.

 

What is 25 to the fourth power?          

 

To do it manually:               Multiply 25 x 25 x 25 x 25 and you'll get the answer. 

                                          (Note that there are 4 of those 25's.) 

 

To do it on a calculator:      Key in 25

                                          Tap the XY button             

                                          Tap the 4 button             

                                          Tap the = button.

If all s/he needed was the answer, that could be obtained from the answers in the back of the textbook.  The student needs to know how to get there.
